Sennheiser MD 421-II

Sennheiser MD 421-II is one of the world’s most recognized dynamic microphones, known for its clarity, durability, and versatility. Featuring a cardioid polar pattern, high SPL handling, and a five-position bass roll-off switch, the MD 421-II delivers exceptional performance across a wide range of studio and live applications.

The cardioid pickup pattern ensures excellent feedback rejection, making it ideal for loud stage environments and close-miking instruments without unwanted bleed. The five-stage low-frequency control allows precise shaping of the proximity effect, enabling natural, clean sound for both vocals and instruments. Its robust fiberglass-reinforced housing and stainless steel grille provide outstanding reliability in demanding conditions, while the internal acoustic design guarantees detailed low-frequency response and protection from dust and moisture.

Whether used on drums, guitar amps, brass, or broadcast vocals, the MD 421-II remains a studio and stage classic, prized for its natural tone and adaptability. It comes complete with a dedicated stand mount for secure placement.
